Inth'e inachinepas herein shown the meat'is delivered iii minced -form and I as a i-lat strip from'a nozzle and :is discharged onto a eb or sheet of paper travelling substantially in the direction of the feed of the meat "from the nozzle and to \vhich the meat adheres."

.1 is a frame inwhieh at one end thereof is arranged a mincing apparatus 01" W611, knowirform in'cludingia housing 2 and-a spiral mincing element 3 in the" housing mounted on and adapted to-rotate with a horizontal longitudinal shaft 1 journaled-in the frame, the housing having ahopper through which the mentor other substancetohe minced is fed to the apparatus The outlet nozzle 6 of the housingfhas a cross sectional form such as will deliver the minced contentin a fiatstrip the vertical section of which \v'll be apparent fron the transverse sectional view of any of-theca'kes or patties A formedtherefrom and shown in Fig, 4. #All the moving parts of theimae'hine are driven from shaft l, which drives an othershaft. paralleltherewith, through gearing f8, 9v and,10-.

Shaft 17 is journaled; atone side oft-hemaehine'in a bearing ll -andalso abearing '11" afforded by one of a pair ofuprighjts 1212*01" the i'rani'e. In suitablebearings in-the'se up right-sis journaled a horizontal crossshaft 13 which isingear with shaft 7 tlirough an, interm'eshing Worm l4 and -wo 'm-wheel 15. This. shaft has fi ed thereon 'a pair of sproelzet ivheels 16-; engaged by endless chains lTa'lsoengaging two other pairs 18 18 of sproekeuwhe'els, the chains extending around these severalpairs; the arrangement of the three pairs ofsprocket-Wheels is such that the chains assume in side elevatio'n triangular form Withjthe has'esofthe triangles approximately horizontal. a 1 A wide ro'ller 19 having a pairo'tsproeliet Wheels 19 is arranged under-the outlet 6 of thoimincing apparatus, and a pair ofnarrow rollers 20 '(Fig. are-arranged below and near the spireeketryheels 18, the-shafts'of said-rollers being ournaled in the, frame. In

horizontal alinement with the sprocket-j avheels 19 is ;-a set of three other pairs of sprocket-Wheels 21, the sprocket-Wheels 0t each pairin such set inthis case being not mounted "onjla: shaft but on individual stub: shafts 22 (Ei'g-AJ toafi'ord a clear vertical passage in this part ofthe machine, as will appear.

outlet 6, so that delivery of the minced (011* tent from the nunenig apparatus takes place in such plane onto a paper (or other ilexlble) sheet or web B which is advanced by and upon said wheels and between the same and the chains, being also supported for its full width by the roller 19 and as to its margins by rollers 20 and having perforations B along its margins engaged and thus gripped by the teeth of such wheels. The sheet or web B is withdrawn from aroll B thereof between which and the roller 19 itextends between rollers 23, 2% having at their ends coacting perforating means formed by pcripheral per'lbrating teeth 2?) on one and corrcspoinling recesses or dies 24-, on the other. The outlet 6 is narrower (Fig. 3) than the space between the two lines 13 of perforations which will be formed by said means in the web B. As will appear, s rocket-wheels 21 are the draft means for t 1e web 15; the web is progressively cut away as at B (Fig. 5) between the two rows of wheels 21 (one at each side of the machine). leaving its margins 13' subject to the draft of such means. i

The operation of. forming into cakes or patties the strip of minced material A, which is fed from the outlet 6 at approximately the same rate as the paper web B is advanced, is performed by very simple means as follows: 25 is a blade extending across the path of and above the paper web and formed with twocarrying arms 25 which are pivoted to the frame at 26, the whole constituting a lever. This lever normally stands raised, but at intervals (by means to be described) it descends and divides the strip A, allowing the portion A (or cake) detached by it to travel along with the web B while it checks the feed of the material behind it, in the example actually stopping such feed at the outlet. so that the strip is not rnabfornied; the blade is of course not sufficiently sharp to sever the web B. The blade in descending and severing strip A There may 'ie a table 27 (F l and to support the paper web, loaded with the strip A fed thereto, between the pair of sprocketwheels 19 and the set of sprocket-whcels 2i.

When the web B has advanced to the stage where its charge or cake A is flanked by the s n'ocket-wheels 21 it is supported by the two rows of these wheels. oneon each side, being stretched between them and held by their teeth engaging in its perforations. A three-sided rectangular knife is now to descend and cut a rectangle 15 from such strip two sides of which will be inside of and parallel with the perforations, so that such rectangle. with its chargeoi' cake A thereon, will become a detached and completed unit and may pass down through the pas-r e mentioned as existing between the two rows of wheels 21. This knife, 28, is also a lever, fulcruined onthe sliaft of sprocket-wheels 18, its two arms as Well as its transverse portion having all sharp paper cutting edges; the rear edge 27" of table 27 and fixed blades 29 (Figs. 3 and 4;) may coact, shoal-fashion, with the three cutting edges of this knife. The perforated marginal portions or ribbons ll forming the waste of web B resulting from this shearing travel over rollers 20 and may be received in any receptacle 29, Fig. 1.

The movement of the blade 25 should be such that it will remain dinvnfor a. time (so as after cutting off the take A to allow the latter to be carried forward by the paper web I? and thus suitably spaced from the content of the niincing apparatus which is to continue to be delivered therefrom as a strip) and remain up for a time (or until enough of the strip A has passed to form a cake of the proper size). For this purpose the blade 25 has pivoted to one of its arms 25 an upstanding stem 30 gijiided vertically in a hole 31 of an extension of the upright 12 and having a foot-piece thereon between which and said extension a spiral synjiug 33 is coiled, pressing the stern and hence the blade down ardly. The stem has a lateral notch 30 in which is engaged a pivoted latch 31 spring-held against the stem. The gearing by which shaft 13 is driven from the shaft l is such that shaft 13 complctes a revolution for a predetermined extent of feed of the strip A (or enough to form a cake of the desired size). Sprocket wheel. 15 is made a canrby having a hump 34; thereon, and on each revolution of shaft 123 this hump engages and shifts the latch clear of the stern, so that the blade falls and cuts off and thus forms a cake A. On shaft 7 is a cam ill) engagcablo with footpiece 32 to raise the blade. The blade remains down until a predeternlined space has been formed between the cake A it has cut oil and the content of the niincing apparatus, whereupon it is quickly raised by cam 3.3; in the present example this can) active with greater 'l'requency than cam hump 3 because of the gear ratio of 1-it15, wherefore soon after the blade falls it is again raised and relatchcd, its rise being quick (to avoid undue interference with the following portion of strip A) because of the shape of ram 35 (Fig. 7). i

The knife 28 performs a downward and back stroke without pause. For this purpose there are the parts 36. 37, 37'', 3S, 3%) and 40 formed and cooperating the san ie as the parts 250, 31, Ell, 232, 2-53 and 34 already described, the cam 4-1 which is o 'ierative on the foot-piece 38 having a shape (Fig. 7) calculated to effect instant return of the knife. Such instant return. is necessary in order to prevent interference. of the knife; with thenext-followingcake, especially the spaces between cakes are narrow.-

As each unit (comprisinga cake A'and itspaper rectangle or integun'ientBF). is, cut

oil it is received on a. platform. which de: scends in lntermlttent movements and. in

" proper time. so. that the units Will be deu the chains.

The two upper shafts are, by bevel gearinglG, intcrgeared with. a shaft 37: so that the twopairs of chains move in unison.
